*BOOM! BOOM! BOOM!*

Army from 3 allied kingdoms of Besnia, Argumus, and Unicrown got bombarded by unknown pyramid-shaped fort.

They don't know how that fort can attack them with such great distances, even their magicians magic can't even do a thing to that fort.

Apparently, the fort they got fights with is not even a normal fort they always know.

In other side, someone in their late teens sipping a cup of tea in the fort watch tower. With glistering silver hair, a rather pale skin, he chuckled when he sees the army in the outside get bombarded nonstop.

"How foolish you are, ignoring my peace letters that I send to you"

Shirozaki Sora, 'intruder' from world called earth, his intentions is unknown.

P.S. this series will be on indefinite hiatus, maybe I'll rewrite the whole thing in the future (if I ever remember that is)
